Abstract Scope In the present work, nanostructured porous SiO2 microspheres were developed for future drug release applications of doxorubicin. The glass has a nominal composition of 65.6SiO2 27.8 B 2 O 3 6.0Na 2 O0.6Al 2 O 3 weight percent. Microspheres with a regular morphology and 25-35m size were made by flame spheroidization method. The porous microspheres were obtained by a thermal separation treatment at 660C for 6 and 10 hours so two immiscible phases were obtained one is rich in silica and the other one is rich in boron and sodium. After the lixiviation for 2 and 4 days, SEM images showed a greater interconnectivity of the pores as the phase separation time increased. The composition is mostly SiO2 studied by EDS and XPS Spectrofluorimetry of intensity vs concentration of doxorubicin showed a LogNormal distribution in deionized water. These results are important to relate release studies and pi-stacking of the drug.
